Firstly, what is cold porcelain? "Cold porcelain is not real porcelain, it got its name because the finished product looks like porcelain. It is air dry clay that does not require firing or heating of any kind." It's basically: glue and cornstarch clay. It's a cheap alternative to polymer clay that you can make at home! (Or buy in the store but that defeats the point!) I've seen many beautiful and delicate sculptures made from it. (All images taken from deviantart and the sculptures belong to their respective artists: Veggies, Kirara, and Mew) All recipes for cold porcelain contain glue and cornstarch and have the same basic instructions: combine ingredients in a pot over medium heat and stir until the mixture pulls away from the sides. Cold porcelain dries semi translucent and you can add paint to tint it. Something to keep in mind: the color darkens as it dries and it shrinks (which can cause cracking it it's not kneaded enough). After a researched several sites, I settled on this one to try first because the ingredients were the simplest and easiest to find. I found the first cold porcelain recipe I tried from squidoo.com. 1 cup pva glue (white glue like Elmer's Glue All) 1 cup cornstarch 1 tablespoon mineral oil (baby oil) 1 tablespoon lemon juice, witch-hazel, or clove oil (I used lemon juice which is not pictured.) I did not like this recipe. The ingredients required a lot of stirring and took about 10 minutes to solidify. Afterward, the clay was really sticky so the cleanup of my pot and spoon required a lot of scrubbing. I had to add cornstarch to be able to use it and then when it became too dry I added more mineral oil to moisturize it again (like the instructions say) but the mineral oil didn't fully mix with the already-made clay. Pieces of clay didn't want to combine or stick to one another properly. Everything I made cracked no matter what I did and the clay itself was just difficult to work with. My second attempt went much better! The ingredients were a little harder to find because I didn't know where to get glycerin or what cold cream was! I used the recipe from craftstylish.com. 3/4 cup white glue 1/2 cup water (not pictured.) 1 teaspoon cold cream (such as Pond's) 1 teaspoon glycerin 1 cup cornstarch, plus additional for dusting your hands For those who are ignorant like me, cold cream is used to remove make-up so it is found with cosmetics. I found my glycerin in the pharmacy department of Wal-Mart near the bandages. It was on a bottom shelf. Glycerin is also used in baking (for icing, fondant, candy, etc.) so it should also be in the cake decorating section of your local craft store. I'm sad to say this recipe is actually worse than the previous recipe. I can't get it to dry without cracking. TO BE CONTINUED... |

I would love to see an update to this! I also, am looking for a good one!
ReplyDeleteI prefer the first recipe.
ReplyDeleteI use tea tree oil to prevent mol, found a tupperware with 6 month old CCP, was fine. smells nice too.
I microwave at 30 seconds intervals, stirring until holds shape.
Knead the heck outta it while still hot.
i'm also into cold porcelain just recently. i used Shangeetah Shah's recipe which you can find in youtube.. It was my first time in making it, but it turned out very nice, its soft, malleable and no cracks at all.. It dries out quickly maybe because i was in a tropical country.. and also, i've noticed that cracking has a lot to do with the kneading, especially after you've added acrylic paint in it, be sure to knead it properly, otherwise it will crack.. hope this helps..=)
ReplyDeleteWhen I finish mixing all the ingredians, I put it in the microvave for 30 seconds, take it out, stir it, put it in the microvave again for 30 seconds, stir it, and repeat the procces one more time.
ReplyDeleteI also use the first recipe consistently. I tried the 2nd recipe today and I don't like it. It dries far to fast and cracks before it is dry. I will go back to the first recipe and use the microwave like I did before
ReplyDeleteGreat, thank you !! I have a few new recipes for cold porcelain! http://anri-irene.blogspot.hu
ReplyDeleteI use Santee Shah's recipe (I add 1/2 teaspoon of white vinegar) and I have had excellent results1 http://www.figurines-sculpture.com/cold-porcelain-recipe.html
ReplyDeleteyou can see some of my stuff at www.facebook.com/dawnssong4u and or Google: dawn bigelow dawnssong4u ! Happy arting all!
The last recipe is actually correct. Take out the water. The water is what's causing your porcelain to crack. I've been using it now for years and my first attempt was successful. I've never had any cracks.
ReplyDeleteI use the Elmers glue, cornstarch, glycerin, white vinegar And for a while I was using canola oil. I tried baby oil as well. Even made it with clear Elmers glue but it took a lot more corn starch
I only use the Ponds cold cream, or any generic brand, to shield my hands from the heat while needing it afterwards. And I also use the cold cream while working with it
But it's the water that is causing cracks so not even a drop should be used. At any point
Hello, how much vinegar & RU using 3/4 c glue to 1 c cornstarch? Thks. Ella

ReplyDeleteI have been making a selling cold porcelain product for 25 years. If you substitute tacky glue for the regular school glue you will get much less cracking since it's the evaporation of the water that causes the shrinkage. Also let your finished pieces cure away from drafts. The only water you should use is just enough to coat your hands to knead into the clay when it starts to dry out.
ReplyDeleteIs Elmers glue advisable?
Delete30 seconds in the microwave is too long. 15 seconds mix for a minute and repeat two times.
